4 Answers - Do guard cells perform photosynthesis? - Quora

They are only found in plant cells because animal cells do not need to perform photosynthesis.

LabBench Activity How Do Guard Cells Function

Guard cells are specialized cells in the epidermis of leaves, stems and other organs that are Oxygen (O2), produced as a byproduct of photosynthesis, exits the plant via the stomata.

These are the ingredients and products of photosynthesis and cellular respiration.

Guard cells are cells surrounding each stoma

Terminal buds have special tissue, called , consisting of cells that can divide indefinitely.
Phyla: The phyla in the kingdom Plantae include: Ginkgophyta, Lycophyta (lower ferns like club mosses), Pterophyta (ferns), Psilophyta (whisk ferns), (flowering plants), Gnetophyta, Sphenophyta, Coniferophyta (conifers), Cycadophyta (cycads), Sphenophyta, and (mosses, liverworts, hornworts).

Vacuoles are only found in plant cells but there are vesicles to replace them in animal cells.

One of the paired epidermal cells that control the opening and closing of a stoma in plant tissue.


Guard cell photosynthesis and stomatal function - …

Stomata are cellular pores on the aerial surface of plants. They open to allow the uptake of carbon dioxide and close to limit water loss, and thus are essential for plant growth and homeostasis. Stomata, which are common to almost all land plants, represent a critical evolutionary innovation of early land plants. A stoma is formed by a pair of guard cells, which are the final products of a specialised cell lineage. Mature guard cells mediate stomatal opening and closing by regulating the fluxes of ions, and hence water, in and out of the cells. To maximise fitness in the ever‐changing environments, both the development and movement of the stomatal guard cells are highly responsive to diverse environmental signals. These stomatal responses will likely play a key role in plant adaptation and agricultural production in the face of global climate change.

2 Answers - Why do guard cells have chloroplasts? - …

Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis.

Plant Guard Cells: Function & Definition - Video & …

Leaves are adapted for photosynthesis by having a large surface area, and contain stomata (openings) to allow carbon dioxide into the leaf. These design features can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf by diffusion.

Plants have leaves which contain guard cells and …
